Open wide: Identifying North Atlantic right whale feeding behaviour using camera-validated kinematic data and machine learning

Caption

Annotated images from CATs tag video diary deployments on North Atlantic right whales (Eubalaena glacialis) in the Gulf of St Lawrence, Canada. Reading left to right by row: (a) Annotated confirmed mouth open event from 10th July 2024 deployment on EG4903. (b) Annotated confirmed mouth open event from 7th July 2024 deployment on Tally, EG4612. (c) Unidentified conspecific feeding close to Warrior, #EG3942, on 13th July 2024, who is also presumed to be feeding. (d) Subsurface interaction between Peregrine, EG1628 and another individual on 11th July 2024. (e) Evidence of synchronised dive timing between Nimbus, EG3812, and another individual on 6th July 2024. (f) Subsurface body contact between Nimbus, EG3812 and another individual on 6th July 2024, presumably the same individual seen in the previous image. (f) & (g) Benthic interaction of EG5305, individual dove to the seafloor on three consecutive dives, rolled, and seemingly dragged its back on the seafloor.
